Research/Experience

MIT Plasma Science and Fusion Center (Cambridge, MA), 2016 – present

Postdoctoral Associate

  • Research on disruptions and disruption warning algorithms through Machine Learning techniques across many different devices, from Alcator C-Mod and DIII-D, to EAST and KSTAR in Asia.
  • Realization of real time algorithms, eventually integrated in the Plasma Control System.
  • Leader of MIT-PSFC Machine Learning Working Group.

UniCredit Business Integrated Solutions S.C.p.A., Milan, Italy, 2015 –2016

Data Scientist

  • Data Scientist in UBIS ScpA in the Big Data group. Worked on Big Data demands from ideation, proof of value to delivery process and contributed to create statistical models that responded to specific business needs, such as Customer Relationship Management. Developed innovative data analysis solutions through advanced statistics and Machine Learning.

Consorzio RFX, National Research Council (CNR), Padua, Italy, 2012 – 2015

PhD student and Research Scientist

  • Investigated local transport properties and their modulation depending on the magnetic topology in presence of externally applied magnetic perturbations. Studied the effects that relaxation events inside the plasma have on its boundary topology. Analysis were conducted on RFX-mod. The link between magnetic topology and local transport measurements was explored through a field line tracing code.
  • Installation and analysis of data coming from the ExB probe, previously used on COMPASS and ASDEX-Upgrade.

Institute of Plasma Physics, CAS CR, Prague, Czech Republic, May 2014

Visiting Research Scientist

  • One-month collaboration project under the Work Package ER-01/ENEA_RFX-02 “Magnetic reconnection in fusion plasmas”, approved by the EUROFUSION organization. Analysis of measurements of ion temperature profile coming from the ExB probe installed on COMPASS.

University of Pisa , Master Thesis, 2018 – 2011

  • Development of a transfer model, by studying a two neutron process taking place in the reaction 13C(18O,16O)15C at 84 MeV incident beam energy. The experiment was realized using the large acceptance magnetic spectrometer MAGNEX, at LNS ("Laboratori Nazionali del Sud") laboratories.
  • Theoretical calculations were consistent with the experimental data and capable of describing the background that lays below the resonances by considering only the elastic part of the transfer to the continuum reaction: 14C(17O,16O)15C.
